] This invention relates to a treatment for textile fabrics and especially to apparatus for practising the treatment.

One object of this-invention is to provide 5 for operating upon cloth, which may already be finished in the sense of having been bleached, mercerized, printed, dyed, calendered, st'arched, ironed or polished, or any of these, either-inthe yarn or on a finished web,

or both, in such a way as to secure and set in the cloth a maximum contraction in one dimension of the web. Another object is to accomplish this without injury to the finished effect of the cloth treated. Another obj ect is to cause and fix a rearrangement of the component yarns if the web is woven, or of the loop structure if the web is knit, withthe result that'at least one dimension of the treated web is shrunken, made as short or as much contracted as it is possible to make the web by washing 0r bleaching or other usual cleansing or laundry treatments, so that articles, garments 0r garment-sections cut from the web will be unalterable in that dimension in 'use, or if alterable will stretch sli htly rather than shrink, and thus not be su ject to shrinkage as a detrimental incident to use of the article or garmentafter repeated cleansings. While the invention is useful 0 for the treatment of many different kinds of textile fabric, a typical and preferred utility is in the manufacture of articles of haberdashery from washable linen, cotton, silk, artificial silk or woolen cloth. Clothes in general and particularly shirts and shirt collars and cuffs, waist, neck and arm bands are most susceptible to damage from shrinkage, and a principal application of this in vention is in the pre-cutting and pre-assem- 1 bly treatment of cloths for the said uses to prevent damaging shrinkage when the garment is washed and ironed in use.

It is customary in this manufacture to conserve the trade finish of the web material in new garments for sale. In shirtings, for

example, the applied glossyfinishes of linen,

the glosses of many mercerized cottons, of certain artificial strands of rayon or other syn-' thetic silks, and surface finishes of prints and many plain fabrics do not survive unaltered their first laundry treatment. Purchasers-andusers of these goods are familiar with and tolerate these effects, but they are not attracted by new garments which in part show the final effect of laundry treatment and in part do not. This has had the effect of deterring the maker'from subjecting any part of a garment or the cloth before making up -to laundry treatments of sufiicient effect to attain the expectedshrinkage in use. If a garment or the cloth is shrunk by laundry treatment prior to marketing any prior treatment for this of which I am aware, including repeated washings and dryings, is either no guarantee against future shrinkage or else causes such depreciation of' the subsequentlife of the garment as to make itssale as a new garment scarcely ethical.- Theefl'ect of shrinkage so much depends on the nature .of the washing treatment that it is quite impossible accurately to forecast what the size (length between buttonholes) of an unshrunken cotton, for example, will be after its fifth visit. for example, to a laundry.

Collar manufacturers have heretofore shrunk the cloth for white collars, for example, by standard laundry treatments, but have never attained wholly exact results for the finished product after wear except with cloth of certain very dense weaves. The col- .lars, cuffs, arm'aud n'eck bands of shirts increasingly are demanded to be of the same material as the body of the garment, and whereas shrinkage of the order of two or three one-hundr'edths in adimension of the body'of such garment is of no importance, in the said named parts such a degree of shrinkage may prevent its use; if allowed for by shrinkage of parts or all of the fabric used in such a garment without disturbing the gloss or other characteristics of surface of the component yarns, and permits preshrunk parts to be-made of uniform appearance with the remainder of the garment.

In order to cause a definite change in the position of component yarns in a woven web,

and to fix the changed relation, this invention includes mechanism for automatically effecting this result. In a preferred form in connection with which the invention will be described, such a machine may include devices dealing witha' continuous web for stretching one system of interwoven warp and weft, preferably the wefts, devices for securing freedom for rearrangement of the other systeni of yarns, means for temporarily softening stiffening inclusions tending to prevent any rearrangement, and meansfor resetting and stiffening the yarns intheir new arrangement. '1 he machine includes devices for accurately determining the quantitative ratio of shrinkage, and inay include feeding and dofiing means for handling continuous webs, and automatic devices for dealing with variable widths of the web treated.

Fig. 12 is a. diagram of comparative longitudinal sections of the web before and after treatment explanatory of the change effected in the web treated.

Referring to Fig. 12, any cloth typified by the cloth shown in warpwise or longitudinal section at W of plain or one-and-one weave comprises warps 'w and wefts f interwoven by initial passage each first to one side and-then to another of a yarn of the other yarn system and the web. When, as is typidue'to increase of diameter of the yarns,-

which swell when free, and consequent decrease of length But principally the lessened length of warp or weft is due to increased amplitude of the crinkles of curva-.

ture due to enlarged diameter of the yarn of the other system. The cloth is thicker when shrunk;'-'

According to this invention I cause the yarns of one system to lie substantially straight, andin the median plane, by placing the yarns of that system each under longitudinal tension and releasing the yarns of the other system, and thereafter setting bystiffening (and compacting, pressing, dressing or otherwise if desired) the yarns. As shown at W for example, the wefts f have been brought to the median plane by endwise tension on them during freedom of the warps 'w, whereupon the warps w take on deeper curves, as they must do to pass. on oppositesides of successive wefts in their new position. The wefts f are. now substantially straight from side to side of the fabric; where the web in its state W had a longitudinal dimension 6 including'a certain number of wefts f, in its state W the same number of wefts are included'in the shorter dimension a. Straightening the wefts 7 among other things involved moving each curved run of the weft above awarp in the direc- I tion of the arrows'in the upper part of Fig.

12 in relation to that warp; this required more warp length; this could come only from.

a longitudinal distance, since each warp everywhere was under the same stress from a multiplicity of wefts all requiring more warp to straighten; the longitudinal dimension of the fabric necessarily shortens to supply this length of warp not required when the cloth was in its state W.

The converse of this is'that if the longitudinal or warpdimension of the cloth is prevented from yielding, noamount of stress on the wefts f will be effective to straighten them or more deeply curve the warps. So far as I am aware, all tentering, stretching and drying machines or processes heretofore in use have applied longitudinal tension to the cloth, and their operation has therefore done nothing to shrink the cloth in either dimension, but on the contrary has often imposed on the warp and weft yarns alike an elongating stress, which is promptly countervailed by shrinkage when the cloth is next wet.

I preferably perform the steps of shrinking any resistance to shrinking, take-up, oi

and seizing the lateral margins or selvages of the cloth in such a way as to avoid imposcloth in gripping devices quite obviously prevent the cloth 'at' the margins from re-' sponding by shrinking to the effect of elongating the wefts; the ordinary devices for feeding. and applyin a web of cloth. to the stretching devicesv 0 tenter frames invariably depend on longitudinal stress on the cloth for part of the effect of impaling or gripping the cloth at its margins; and such apparatus, machines and systems of which I am aware which make. the fabric moist, or

cause it to be made moist in progress of the operation and subsequently dry the cloth have no provision whatever for ermitting recession of length in the direction of the warps.

. web entering the machine, and adjusting-f Referring now to Fig. 1 the preferred form of the machine of this invention comprises supporting crossv frames 1, which may be of' any suitable design and providedwith any.

type of longitudinal stiffening strut, for example, as shown at 2. The frames 1 areerected at suitable. distances apart to provide for a considerable travel of the web. It is desired to provide in the machine means for specially feeding or applying the already finished web to devices for stretching it weftwise; means for softening stiffening inclusions, if any, in the web treated, preferably in the form of devices for progressively steaming .the fabric during a considerable length of travel, corresponding to the exertion of lateral stretching; and devices for drying the fabric in its readjusted form following the completion of the stretching to set the stretch applied to the wefts. For wholly automatic operation a recommended form of the machine includes automatically acting devices sensitive to the width of the devices for the stretching devices responsive to the indications of these sensitive devices and acting automatically to set the position of the grasping instruments and the degree of their subsequent separation to stretch the fabric. A recommended form of the machine also contains devices for dofiing the shrunk, set and/ or dried cloth without imposing upon it any longitudinal stress.

Referring again to Figs. 1 and 2, there may be provided at the extreme ends of the machine transverse shafts 5 and 6 respectively, carrying ftrans versely adjustable sprocket For these purposesables the end of wheels 7 and 8 on hubs 7 ,8 splined on shaft 5. These sprocket wheels support and drive two otherwise inde endent chains 10 and 11, see Figs. 3-, 4, 5 an 6, each'made up of holl'ow links 12 and solid links 13, each of said links carrying upon one face aT headed projection 14 bored and providedwith impaling pins 15 at evenly spaced distances. The'T headed construction of the projection 14 en- I pins of two adjacent links to be the same distance apart as the other pins 15 tion.

Either the shaft 5 or the shaft 6 may be a driven member relied upon to move each of thechains. 10 and 11 at a predetermined rate longitudinally of the machine,

In the form shown, the shaft 6 is the driver, the machine being provided with cone pulleys at 16 suitabl geared to said shaft 6 upon which the hu s18 for the sprocket wheels 8 are 'splined. These hubs 18 may be provided with concentric grooves 19, 19 for forks 20 adapted to slide on the adjacent end of frame 1 and provided, as presently mentioned, with a transverse adjusting screw shaft 21 geared at 22 to longitudinal shaft 23, Fig. 2, in turn gearedat 24 to a similar shaft'25. The shafts '21 and 25 are oppositely threadedv at their opposite ends, and engage threaded openings in cross head slides 26, which as best shown in Fig. 3 may be provided at any of the frames 1 to slide in slots 27 in the transverse struts 28 of the respective frame members.

The forks 20 for the sprockets 8, for examin the body of the T headed projecple, ma be bolted on the end face of the slides 26in t e same manner as the similar structure shown in Fig. 4.

Referring again to Fig. 2, the chains 10 and 11 are respectively guided in channel "slideways 30, 31 which, as best shown in Fig. 2, may be providedin sections extendln from frame 1 to frame 1, the said sections aving overlapping lugs at 32 bored for a connecting bolt 33, and adapting the channels 30,31 to be moved to define a diverging path for the tenter chains 10 or 11 between any two ormore frames 1; The return .run of the chains 10 and 11 may be carried in similar channel bars 80, 31". vThe link sections of the runs 30, 31 of the guide for the chains 10 and 11 may be mounted on the lower end of the slides 26, v

and the bolts 33 connecting the sections of the guide channels30, 31 of the upper runiof the chains 10 and 11 respectively may? be screwed intoa hole in and be moved by the upper head of the cross heads 26. It will therefore beseen that the provision of transversethreaded screw shafts 35, one of which is illustrated in Fig. 3, and is typical of the others, will enable the channels carried by the cross heads 26 to be adjusted laterally without disturbing the relative position of any part of the component links of these channels in respect to another part. In practice, it

' the lateral is preferred to cause the stretching divergence of the chains 10, 11 over the middle and towards the end of a part of travel of the web of the cloth through an atmosphere of steam, and as shown in Fig. 2, a divergence of the appropriate sections of the channels 30,31 may be fixed by the original adjustment of a screw shaft 36 in relation to another screw shaft 37 controlling the respective slides 26 at two adjacent frames 1. These screw shafts are geared at 38, 39 respectively to a longitudinal shaft 40, which may be a mere extension of the shaft 23. The shaft 40 may carry a sprocket at 41, rotation of which will set the width apart of the channels, 30, 81, 30, 31 the sprockets 7 and the sprockets 8 in a like way.

As shown in Fig. 4, a preferred construction of the cross heads 26 at the left end frame 1 of the machine comprises forks 20* similar to forks 2O bolted on the respectiveslides 26 and taking into an annular slot 18 in the hub of each oft-he sprocket wheels 7, which of course is free to slide on its shaft 5. The upper head 26 of the slide 26 at the left-hand end of the machine is relied upon to adjust position of other parts presently mentioned.

The first few sections of the machine as de- 3e fined by the frames 1 to the right of its entrance end (at the left of Fig. 1) is preferably provided with steaming pipes which may be perforated as shown at 51, extend longi tudinally under the upper run of a web traveling with the chains 10 or 11, each pipe being provided with an individual valve at 52 controlling its connection to a header 53 connected to a supply pipe 54 having. a main valve 55. Over the machine and above the pipes 50 a suitable hood 56 and exhaust main 57 may be provided to collect steam above the upper surface of the web traveling in the machine and dispose ofits elesewhere than in the room containing the machine. Any desired number of sections defined by frames 1 of the machine at the right-hand end of Fig. 1 and Fig. 2 may be provided with longitudinally extending heating pipes 60 which may be connected ma suitable header 61 to supply pipe 62 and main valve 63. As shown, the heating pipes 60 extend beneath the course of travel of the web after the web has been stretched. The efiect of the heat radiated by the pipes 60 is to set the cloth in its laterally stretched and longitudinally shrunkened condition.

' A cloth web W entering the machine, see

Figs. 1 and 2, may be fed from any suitable supply, for example a book-folded continuous length carried on a truck 65 from which the web travelsoverhead to a guide roller 66 past tension bars 67 for the removal of longitudinal wrinkles, if desirable or necessary over any suitable scrimp bar device, not shown, which may occupy the position shown to the first of two tractor rollers and 71 relied upon to provide the entire energy of longitudinal feed of the entering web. One or both of these rolls, for example, the roll 71, may be a sand or rubber covered roller for maximum tractive efiect on cloth, and the speed of the surface of this roller sets the entering speed of the web W.

- Between the tension device 67 and the roll 68, in the preferred form, one of the well known F oxwell guides shown at 69 may be relied upon, to laterally position the cloth without longitudinal wrinkles prior to its passage under the roll 70 and over the roll 71. In the normal operation of the machine the surface of the roll 71 moves at a linear rate as much faster than the chains 10 and 11 as is required to provide a suflicient slack of fabric to accommodate the shrinkage induced by the subsequent stretching of the wefts, and the effect illustrated in Fig. 12.

Referring now to Fig. 8, if it is desired to shrink the fabric one inch in the yard, the linear speed of the surface 71 should cause travel .027778 times as fast as does the chain 10, and a lesser or greater ratio of slack of the application of the fabric to the impaling pins 15 should be provided for to induce the effect of Fig. 12. But a mere correct setting of rates of the roller 71 and the chain 10 will not alone suffice. It is desirable that so much of the fabric as extends between any two adjacent pins 15 should be applied to those pins so that its ratio of slack, as compared with the distance apart of centers of adjacent pins, corresponds to the ratio of shrinkage to be attained. For this purpose, I prefer to resort to an applicator or impaling device which I prefer to make in two parts, one providing that the edges of the material are impaled upon the pins with the proper ratio of slack, and the other completing the impalement by forcing the fabric down on the pins 15 into contact with the faces of the pro jections 14.

Referring now to Figs. 1, 2, 3, 4 and 8 particularly, in the preferred form the first part of the applicator, for accurately performing the impaling operation, I prefer to make as a brush roller 80, which may be made as two separate disks of suflicient thickness for their work, as best shown in'Figs. 2 and 3, which disks are mounted on hubs 81 preferably free to rotateand slide on a. shaft'82, the hubs of these brush wheels having annular grooves bearing in parallel sided forks 83, Fig. 4, re-

82 there is provided a bearing ring having a place for attaching a cord 85 run over a pulley 86to an adjustable counterweight 87 on each side of the machine, so that the weight of the roll 80 efiective'to act on the web W be adjusted to a nicety. operation referring to Fig. 8 and Fig. 11, the brush' wheels 80 float on the fabric, the diameter of the brush wheel, and the degree of its osculation with the line of the tops of the pins 15 determining the slope at which the web W, having been penetrated by a pin 15 is applied to the point of the next pin 15.

. In turn, the vertical position of the wheel 80 is a function of the rate of feed of the web Why the sand roller 71.

Referring to'Fi 11, if the tangent an le of web W, which as already been imp ed upon the pin 15 to the right in Fig. 11 to the line of the points of said pins when it makes contact with the pin 15 to the left in Fig. 11, is a substantial angle a asshown, it w1ll be apparent that the distance a between the,

centers of pins 15 will thenbear a ratio to the distance I: measured along the slope of the entering fabric which will define the ratio of slack, which will be according to the exa pression T b-a obviously varies as the the versine of the angle 0:. Referring now to I Fig. 12 the relation between the entering web and the finished web, in operation according to the invention, is the numerical relation of hypothenuse b to base a.

The fabric having been impaled according to its slack ratio is slack between every pair of pins 15. The heavier brush wheel 88 on a shaft 89, land 3 the roller having a grooved hub held in a fork 89 of'the plates 84, 3, may be relied upon to force themarglns of the fabric home to full engagement with the pins 15.

. The brush wheel 88 for the pur osesexplained need not be vertically mova 1e in respect to chains 10 and 11, and its shaft 89 may have any ordinary kind of bearing in brackets 91, Fig. 1, fixed on the end frame of the machine. The brushes 88 may be driven by the cloth and chain, but are laterally adjustable to follow changed positions of the chains by the forks 89".

In order to relate the surface speedof roller 71 to thespeed of the chains 10 and 11 according to the recalculated slack ratio, it is ing angular peripheral segments 97 alternat- I ments 97, 97". Adjustment may be read at angular graduations on nut 100 against index 102 on cone 98.

Referring now to Figs. 1, 2 and 6, the treated web runs around the sprockets 8'still on the pin chains, and is preferably dofied without longitudinal stress on the fabric from the return'run of the pin chains. A transverse shaft .105 on one of the frames 1 may be driven by bevels 106 from a shaft 107 and bevels 108on a short shaft 109 geared to the drive pulleys 16. A car 120 on one end of shaft 105 drives a sma l pinion 111 on a shaft 112 having eccentric portions near its ends, over which eccentric portions take forks 113 of dofier levers 115 pivoted in brackets 114 on the under faces of channel guides 30', 31, the forward ends of levers 115 ra idly striking the upper face of the web within the rows of pins 15 during 0 eration. The webW pas'sesunder and to t e right from a roller 116 on transverse shaft 117 geared at 118 to shaft 105. t y

In order to control the lateral position of the tentering chains and their accessories, the machine may include sensitive devices to feel the position of the edges of the web 011- tering it, and means res nsive to the indications of said devices cit shifting the lat-- eral position of the chains, the fabric impaling means, and the channel guides. For example, edge-detectors 110 made as circuitclosing bell-cranklevers may be mounted on a transverse strut to feel the web edges between feed roll 71 and brush rolls 80. The

levers close one or another circuit (not shown) of a reversm connection to motors on a bracket on t e machine frame and geared to the screw shaft 35.. 'When the web edges are normally 'ositioned, the detectors,
